Abstract
The invention relates to a mobile cable for communication vehicles. The mobile cable includes a cable core, a conductive layer, an insulting layer, and a fixing layer. The conductive layer wraps the cable core through the fixing layer. The insulating layer wraps the conductive layer. The conductive layer includes a conductive main body layer. The conductive main body layer is equipped with a plurality of protruding bars that are parallel to the axis of the cable core. Fireproof materials are filled among the plurality of protruding bars. A polyvinyl chloride sheath layer is arranged outside the insulating layer. Multiple polyolefin elastomers are arranged between the polyvinyl chloride sheath layer and the insulating layer. The cable core includes a plurality of independent cores wrapped by shielding layers. A steel wire is arranged in the middle of the cores. Through adoption of the conductive layer and a ground wire, most of electric energy can be guided to the ground wire if a lightning strike occurs for the first time, thereby preventing electric appliances from being damaged. The mobile cable, exhibiting excellent heat resistance and low temperature resistance properties, will not deform in high temperature and severely cold conditions.
Description
Technical field
The present invention relates to a kind of communication truck and move cable, belong to field of cables.
Background technology
Traditional low voltage power transmission cable, when meeting with thunderbolt, can, because cannot discharge the electric energy and power transformation and power consumption equipment a little that electric shock produces in time, also can cause burning of cable itself to blow, generation power-off lamp situation, at the bottom of sale sex simultaneously.
In addition, when communication truck field work, part mobile unit need take out of the local work with a certain distance from communication truck, as antenna, radar etc., wiring and take-up require again certain ageing, and therefore the outside diameter of cable is the smaller the better, and cable weight is more gently better, to reduce workload, increase work efficiency.Each cable separately wiring in the past, waste time and energy, and field work circumstance complication, requirement is had again to the weatherability of cable, the factors such as high temperature, low temperature, ozone, ultraviolet also have impact, because cable frequently pulls and certain self-supporting requirement, also require certain resistance to pulling force and flexibility, former cable is not well positioned to meet these requirements.
Summary of the invention
The technical problem to be solved in the present invention is: overcome communication truck in prior art and move cable technical problem, provides the Novel cable that a kind of lightning protection is fire-retardant.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of communication truck moves cable, comprise cable conductor, conductive layer, insulating barrier and fixed bed, described conductive layer is coated on cable conductor outside by fixed bed, described insulating barrier is wrapped in conductive layer outside, described conductive layer comprises conductive bodies layer, described conductive bodies layer is provided with some raised items being parallel to cable conductor axis, between some described raised items, is filled with fire proofing material; The outside of described insulating barrier is also provided with pvc sheath layer, is provided with multiple polyolefin elastomer between described pvc sheath layer and insulating barrier; Cable core comprises some independent cable cores being coated with screen, and the center of some described cable conductors is provided with steel wire rope.
Described cable conductor by ground wire, video line, many signal cables, feed cable is stranded is formed.
Between described conductive layer and fixed bed, be provided with flame-retardant layer, described flame-retardant layer is made up of the mesh grid of multilayer asbestos.
This conductive layer wrappedly to form by stranded copper wire is oblique outside flame-retardant layer.
Described fixed bed is aeroge, and described cable conductor is fixed in aeroge.
Described fire proofing material is asbestos.
Described insulating barrier is Teflon Withstand voltage layer.
The invention has the beneficial effects as follows:
The first, the present invention is connected with ground wire by arranging conductive layer, when being struck by lightning for the first time, by most of electric energy guiding ground wire, can prevent the damage of electrical appliance to a certain extent.
The second, in cable, Teflon Withstand voltage layer is provided with, Teflon is polytetrafluoroethylene again, there is excellent heat-resisting and low temperature tolerance characteristics, all deformation can not be there is under high temperature severe cold, there is good compressive property, and polyolefin elastomer is provided with between pvc sheath layer and Teflon Withstand voltage layer, there is the effect of good buffering, dispersive pressure, and the outer wall of cable can quick-recovery soon.
Three, aerogel layer of the present invention can be fixed wire, alleviates the weight of cable itself, also when conductive layer meets with electric shock generation thawing, can carry out heat insulation and fire-retardant, prevent wire generation thawing from causing power-off simultaneously.
Four, bulk asbestos braid of the present invention also can carry out certain fire-retardant and heat insulation.
Five, the fire-retardant asbestos between raised item of the present invention can prevent conductive line surfaces from burning, and the high temperature that preventing burns produces causes the thawing of conductive layer.
Six, place steel cable in cable conductor, have stronger stretching resistance, when wiring and the take-up of cable, the damage pulling and cable is brought can be effectively reduced, when being connected to the equipment free suspension of eminence, effectively can share the deadweight of cable, effectively can extend the life-span of cable.
